From prison to palace, treasure vault to private zoo, the magnificent Tower of London has fulfilled many different roles down the centuries.
One of Britain's most iconic structures, this spectacular World Heritage Site offers hours of fascination for visitors curious about the country's rich history - after all, so much of it happened here.
Inside the massive White Tower, built in 1078 by William the Conqueror, is the 17th-century Line of Kings with its remarkable displays of royal armaments and armor.
Other highlights include the famous Crown Jewels exhibition, the Beefeaters, the Royal Mint, and gruesome exhibits about the executions that took place on the grounds.
